ABSTRACT:
A switching dc-to-dc converter employs inductance in series with the source to form an input circuit, and in series with the load to form an output circuit. Suitable switching means alternately connects an energy transfer capacitance in series in the input circuit and in the output circuit. The inductance may be provided by separate windings coupled to form a transformer. To reduce switching ripple in the input circuit, or output circuit, the transformer may be provided with an imbalance of leakage inductance in the primary winding and the secondary winding. The imbalance may be inherent in the design of the transformer, or in the design of the transformer core. In the case of tightly coupled inductances in the transformer, an equivalent imbalance may be achieved by a separate, external inductor connected in series in the input circuit, or the output circuit. In the case of using a separate inductor in series with the source in the input circuit, or the load in the output circuit, the transformer may be replaced with a single inductance. Such a single inductance may be used alone, or with other inductance in series with the load circuit or the input circuit to provide a converter also with an imbalance in the switching current ripple.
